I went on a short vacation to Boston this past weekend and saw the worst crash. Three cars, one of them in the middle, and like everyone else, I wanted to slow down and take a look and see what I could see from the accident. What I could see was not very encouraging. It looked like someone was still in one of the cars. There were police, fire, ambulances everywhere, and I didn’t see anyone trying to get the person out.
Maybe I saw it incorrectly. I was driving and trying to avoid my own accident as people slowed down to gawk. But it just didn’t look good.
I don’t have that much experience with death, perhaps that’s why it struck me. I assumed the person was dead and they just hadn’t removed the body, and it freaked me out for the whole weekend. I couldn’t get the thought out of my head. I ended up parking not too far away and walking back. I was walking somewhere else (on the way to the market) but I made a point of walking by.
By then, there was nothing to see. The cars had been removed from the road, and there were just a couple police waving people through. There was still some glass and such on the ground. That’s all that was left.
It got me thinking about how quickly these things can happen. Someone stops suddenly, someone else drives too fast and doesn’t see. It can take seconds. I drive so often, I don’t usually think about how easily something bad could happen.
And yet, it really could, just like it did to that poor somebody in the car I saw, who was probably just on his way to somewhere he thought was important. Maybe he was on his way to work or maybe he’d taken the day off too and was heading for the same market. That’s a scary thought.
I’m trying not to think this way, and yet, I’m spending my time researching common causes of sudden death. Construction accidents, that doesn’t seem likely for me, but who knows? Things fall off buildings all the time, I bet. Unsafe products, that’s certainly possible. Who can be sure if a can of beans doesn’t have listeria or something in it?
Medical malpractice, I’m not even sure what that means exactly, but I suppose it could happen to me. The wrong pills prescribed, the wrong operation done if I need my appendix out. It’s all possible.
I suppose that’s what is keeping me up and keeping me worried. It’s all possible. It could possibly have been me in that car. How many cars ahead of me was that person when the accident occurred? Perhaps 50 or 100 cars? And how much time would that actually be? If I’d left twenty minutes earlier if I’d been really determined to make an early start…well, I just have to drop it.
But I keep thinking about it anyway.
In order for a person to be a functioning member of society, it is typically expected that they find some form of employment in efforts of earning a living to provide for themselves or their family. In a perfectly functioning world, people would be able to aspire to any job they desired in hopes of one day achieving success. Unfortunately, these conditions do not yet exist. Still, the rising new generations of the world seem to value equality in all forms more than their predecessors. A plethora of work still remains to be done in hopes of creating a more equal world that celebrates differences rather than categorizing each other into specific societal labels.
Workplace inequality has run rampant throughout much of the developed world for decades. Recently though it has become much tenser as urban centers are flooded with diverse new hires. These new hires include many different subgroups in relation to the employee’s background, gender, nationality, etc. For the sake of this argument, the focus will be on gender. Now widely thought of as more of a spectrum instead of the outdated binary model, gender is one of the most easily observed distinctions that differentiate employees in the workplace. Men and women typically congregate in groups of the same sex to collaborate on projects, they mostly have separate changing and restroom facilities, and they exhibit different workplace culture norms. The tension that can develop in workplaces where both sexes coexist can be the catalyst for sexual harassment between individuals to occur. In the state of Texas, there are certain legal protections for employees who have experienced sexual harassment. If the employee experiences sexual harassment in the forms of inappropriate conduct, sexual advancements, and threats to their job security or personal life then they are able to seek counsel from a Texas employment attorney in hopes of receiving fair treatment for any incidents that occur. Standing firmly in opposition of these activities is what is necessary for us to eradicate the grossly normalized behaviors of the harasser. Thankfully now that more women are pursuing higher education and therefore being promoted into esteemed positions we will one day see the gender gap closed. There is a large amount of work to still be done, but through the valiant actions of strong, intelligent women the foundation is being laid for a more inclusive and equal world.
To summarize, the employment sector of humanity is grossly contaminated with unpleasant activities such as sexual harassment. In the state of Texas, an employee can challenge the system in order to have a just result. Although sexual harassment has plagued our society for centuries growing trends of inclusive efforts to end discrimination in all forms are beacons of light for employees all around the world. If we stay focused with advocating for workplace reform so that it promises safe, comfortable environments for all employees the future could see fewer cases of harassment. Through education for employers and employees in the form of inclusive team building exercises and communication workshops, we can effectively combat unjust treatment in the work domain.

When fighting a personal injury case, a lawyer will have many curve balls thrown at him. That means that only a lawyer with an extensive history in the field of personal injury law will be able to be successful at trial. Look for a lawyer with lots of experience behind him, like those at the Abel Law Firm.
When searching for a lawyer to represent you in a personal injury case, you should first be careful to avoid “ambulance chasers”. Check with your local bar association for a list of reputable attorneys. Then outline the details of your case to the prospective attorney and follow any advice you are given.
One of the most common types of personal injury lawsuits involve injury from a defective product. Products on the market are required to be safe for use, and when it can be proven a product is not the manufacturer can be held responsible. You and your lawyer have the obligation of proving the product is not safe.
If you are looking for a reputable personal injury lawyer, investigate what professional groups and organizations are located close to you. A lot of lawyers are dedicated to giving back to the community and thus get involved with organizations in their area. These lawyers are worth hiring and normally come highly recommended.
Doing things the right way and in the right order is incredibly important when you’ve suffered a personal injury. Going about things the wrong way may have a negative impact on your case. Reading up on personal injury is the perfect starting point. Your lawyer will be able to give you the proper guidance and advice regarding your case.
It is interesting to note that while FDTD is based on Maxwell’s equations which describe the behavior and effect of electromagnetism, the term “FDTD” itself was coined to describe the algorithm developed by Kane S. Yee in computational electromagnetism. Maxwell’s equations were based on the work of James Clerk Maxwell, a Scottish mathematician who published its initial form in 1861. Yee, born in China but acquired PhD Applied Mathematics from the University of California in Berkely, described his algorithm in 1966.
Prior to the Yee algorithm, FDTD had been used to solve problems in computational fluid dynamics. In Yee’s work, he suggested a novel way of applying FDTD operators on staggered grids for each of the vector field components in Maxwell’s equations. However, the term finite-difference time-domain (FDTD) itself was coined in by a professor Allen Taflove from the Northwestern University’s McCormick School of Engineering located in Illinois. He had published a paper on the August 1980 IEEE Trans. Electromagnetic Compatibility issue entitled “Application of the finite-difference time-domain method to sinusoidal steady-state electromagnetic penetration problems.”
It was only in 1990 that FDTD techniques became popular in dealing with problems concerning interactions of electromagnetic waves, mostly because of the rise of wireless communication devices, but it is also used to model applications in the fields of geophysics and biomedical imaging and the convenience of computers equipped with fast processors and large memories. There are numerous developers for FDTD application software, including at least 27 which are proprietary, 8 which are open access, and two freeware.
The finite-difference time dimension (FDTD) method for simulating computational electromagnetism is considered the simplest and most efficient way to model the effects of electromagnetism on a certain material or object. The most commercial use of the FDTD model is in mobile communication systems, which makes use of radio frequencies, so engineers have to be able to project how the device will most likely operate in the real world by running simulations. Another application for FDTD is in fiber optics, which is also a technology that relates to communication, and there is an increasing interest in its use in nanotechnology. In a very real way, the FDTD method is used to design and improve the mobile and fixed communication technology we have today.
In terms of scalability, the FDTD method proves robust, merely requiring additional time to do the computation with no changes in the formula. However, while it is a relatively simple method, it requires fine grids to develop a model. FDTD does require a lot of computations which increase exponentially with the number of elements. In order to do an FDTD model, one will require a powerful computer with a lot of memory. It is recommended that a computer running a graphical processing unit (GPU) processor, which is specifically designed to handle large amounts of graphical data in parallel, which is exactly what is needed. How long it takes to complete a simulation will depend on the number of elements in an FDTD simulation and processing speed of the computer. In general, an FDTD model requires 30 bytes of memory per Yee cell and 80 operations per cell, per time step.
Suffering injuries in a truck accident can be a devastating experience to go through. The fact of the matter is that truck accident victims are rarely in a position to be able to afford the costs of medical treatment, loss of income, or other expenses that they may have to deal with as a result of their injuries. For this reason, truck accident victims are often in a position where pursuing compensation from those responsible for their injury may be the only way to get their lives back together.
A recent case from Texas illustrates the ways in which a personal injury suit for truck accident damages can help those whose lives have been impacted by this type of situation. The family of Daniel Rhodes, who died in a truck accident in 2011, was represented by attorney Jim Hart of the Williams Kherkher law firm in Houston, Texas. Hart was able to successfully argue that the companies for which the driver of the truck was working had failed to train him properly, leading to the tragic loss of Daniel Rhodes’ life after the truck driver attempted a dangerous maneuver in trying to return to the road.
The jury in the case found in favor of the plaintiffs and awarded a total of damages in the amount of $11 million, though the two parties afterwards settled out of the court for an undisclosed sum. Nevertheless, this case illustrates how critical the role of a qualified legal professional can be in helping the victims of truck accidents to fight for justice.
Electromagnetism is a fundamental force in nature that establishes the internal properties of all things on Earth. It is a phenomenon that is manifested in the interrelationship between electricity and magnetism, and the interaction of electrons and photons at the atomic and molecular level. The theory confirms that one can be produced by the other and also explains the nature of light.
Electromagnetism is a relatively modern concept. Prior to the 19th century, scientists believed that magnetism and electricity were distinct forces. It was not until scientists from Denmark (Hans Christian Ørsted), France (André-Marie Ampère) and England (Michael Faraday) worked out the dynamics that inextricably linked electricity and magnetism that the idea it was a single force piqued scientific interest. This was formally synthesized in 1865 into the electromagnetic theory by Scottish mathematician and physicist James Clark Maxwell, who had been tasked to transcribe Faraday’s experiments in electricity and magnetism into mathematical terms.
In his set of equations, Maxwell demonstrated that electricity and magnetism traveled in distinct waves through space, and that light itself is the result of the undulations of the electromagnetic waves which travelled at the same velocity as light. Together, electricity, magnetism, and light comprise the electromagnetic field.
However, Maxwell’s publication only became accepted outside of England when Heinrich Hertz, a German physicist, verified his equations in 1886. To add insult to injury, it was only in 1905 when the Theory of Relativity proposed by Albert Einstein that it cemented the notion that electricity and magnetism were two sides of the same coin, although they are by no means the same force.
The significance of the electromagnetic theory is that it became the basis for many of the theories in advanced physics, including quantum mechanics, which speculates on the properties of nano particles in relation to the physical world. Because these particles are so small, they can only be detected by how it affects the electromagnetic field.
The fact of the electricity and magnetism interrelationship being discovered to give way to electromagnetism is hugely relevant when it comes to practical applications in modern life. True, it is the basis for the nebulous and largely theoretical worlds of quantum physics and quantum mechanics, but the fact is for most people it is what makes the world go around.
The basic principle behind how electromagnetism is generated is the core concept of household electricity. The fact that we can turn the power on and off at will is a convenience that we all take for granted but is actually a crucial part of modern living. Because an electromagnetic field produces the energy that makes any gadget or appliance work, its continued presence is necessary to keep the machine or motor going. It is only through the passing of an electrical current that this electromagnetic field can be generated, the modern householder can control when that field is produced by simply flipping a switch. This in turn cuts off or supplies the electrical current that drives the electromagnetic field. Voila! Power at the flick of a finger!
Gadgets that make use of electromagnetism exploit the fact that the flow of electricity dictates when the magnetic field is energized, thus having control of this flow makes the gadget work as needed. An electromagnet is typically constructed of an iron core with a conductor such as copper wound around it which will carry the current that will activate the magnetic field. The strength of the field will depend on the amount of current that passes through the copper coil. A good example would be those large magnets that move heavy metal objects around a junkyard. An electric current energizes the magnet, causing metal to get attracted so that they can be moved. Once the object is in position, the electric current is cut off, causing the magnet to de-energize and release the object.
Common household appliances also use electromagnetism to work, such as televisions, electric fans, door bells, electronic door locks, loudspeakers, audio and video tapes, computers, and storage devices. Mobile phones would not be possible without electromagnetic pulses to carry the signals, and in the medical field, it is used in diagnostic equipment such as the Magnetic Resonance Imaging (MRI) scans. Electromagnets are also used for magnetic levitation (Maglev) trains.
These are just a few of the more obvious uses of electromagnetism. With technology and science developing at lightning speeds, it is entirely possible that there will be more uses for electromagnetism in the future. Right now, it is a crucial part of daily life.
Perhaps one of the more interesting movies electromagnetically speaking is The Core. The basic premise of the movie is that the Earth’s outer core, supposedly the third layer of what makes up the planet, which is believed to be in constant motion, has stalled due to human interference. As a result, the electromagnetic field that surrounds the earth protecting it from the destructive power of the Sun’s cosmic rays has become unstable, creating earthquakes, electrical failure, and general breakdown of basic electronic technology, including pacemakers. The disruption has also caused birds to lose their sense of direction and sends them careening into stone statues to die in front of small children in parks. The mission of the protagonists is to jump start the planet by detonating a series of nuclear bombs at strategic points in the liquid iron of the outer core.
The Earth does have a protective magnetic field around it that protects the surface from being inundated by powerful solar rays that can cause, at the least, serious personal injury from radiation. People are sometimes also injured or contract illnesses from man-made radiation sources. An electromagnetic field is generated from the motion of charged particles, and in the case of the outer core, it is the extremely high heat that sets the charged particles in motion. It is also true that this continuous motion of the liquid metal in the outer core does generate this protective field, which extends to about 78 miles up from the crust (surface of the Earth). Occasionally, fluctuations in the field let in more cosmic rays than usual, affecting communications, power grid networks, and satellite reception, which was demonstrated in the first part of the movie.
It should be noted there are some points in the movie that reeks of bad science, such as the existence of amethysts in the mantle, which is in turn posited to be mostly empty space. While scientists have yet to penetrate to the mantle, known scientific facts make these suggestions highly improbable. However, the movie does base most of its propositions on sound principles, save for the fact that the motion of outer core could be stopped or restarted with existing technology.
There has been a growing concern that because of the proliferation of electrical and electronic gadgets, humans have become more frequently exposed to electromagnetic fields (EMF) at dangerous levels. Reports of increased incidence of anxiety, headaches, decreased sexual appetite, nausea and fatigue have been suggested to have been caused by long-term EMF exposure in the home. These include such homely accoutrements as televisions, microwave ovens, cable, computers, radars, and mobile phones as well as power lines and nuclear power plants.
In general, the average person is exposed to constant doses of low-frequency, non-ionizing EMFs, and there is no evidence to suggest that this has an adverse cumulative effect on the health. The body itself runs on tiny bursts of electrical current resulting from biochemical reactions natural to normal bodily functions.
This is of course a lot lower than the electric current that runs through a construction site worker who accidently touches an exposed live wire, which can certainly pose a significant health threat. For the average person, however, constant low-frequency EMF exposure is generally safe, even when standing (without actual contact) beneath a high voltage power lines.
This bears special mention because there have been allegations that proximity to power lines increases the risk of developing childhood leukemia. Despite numerous studies into the matter (approximately 25,000 and counting), there has been no conclusive evidence that this is so, although it may be prudent to err on the side of caution and avoid prolonged exposure to these areas when possible.
This is not to say that EMFs have no effect on the human body. It induces currents to circulate and depending on how strong the magnetic field is can stimulate muscles and nerves and interfere with biological processes. Overall, however, the body is able to cope with EMF exposure provided it is at non-ionizing levels such as is found in normal everyday life.
